What spec are you guys running in RBGs? What spec do you guys think is the best for overall damage output?

While I do love MM, I dont think its very optimal in rot comps, do you think SV would be a good fit?
My friends who play fire and affliction want me to come back and RBG with them and want to synergize with their specs.

Well I hate to break it to you but the primary objective of a hunter in rbgs these days is to just sit a node and defend. Any lock or spriest with half a brain will outdamage you regardless of what spec you play. Now if you're going to run rbgs for fun with friends then you should be survival just because it's basically the hunter dot spec and spread damage is king in rbgs.
